FREDERIC I. SCARD, OF DEMERARA, BRITISH GUIANA.

EVAPORATING-PAN.

SPECIFICATION forming part of Letters Patent No. 662,976, dated December 4, 1900.

I Application filed October 4, 1899- Serial No. 732,530. (No model.)

To all whom it may concern.

Be it known that I, FREDERIO ISENBART SOARD, a subject of the Queen of Great Britain and Ireland, and a resident of Demerara, British Guiana, have invented certain new and useful Improvements in Defecators for Sugar-Juice and Like Liquors, of which the following is a specification.

This invention has reference to improvements in defecators for sugar-juice and like liquors; and the object of the invention is to so construct the appliance that all the defecation will be efficiently done in a continuous and automatic manner.

In the accompanying two sheets of explanatory drawings, Figures 1 and l represent a longitudinal vertical section of a continuously-acting defecating vessel constructed in accordance with my improvements, half of the vessel being shown on one sheet, Fig. 1, and the other half On the other sheet, Fig. l, the junction being at the dotted line 00 00. Figs. 2 and 2 are corresponding plan views.

The defecating vessel A is of a long troughlike shape, and below it are placed separate steam-heating-jacket chambers B B B each fitted with separate steam-valves b b b and drain-outlets b and these chambers may be maintained at different temperatures.

Adjustable transverse baffle-plates O are fitted at spaced distances apart within the defecating vessel A, projecting down at an inclination from a point below the top of the vessel to near the bottom of the vessel. These plates may be conveniently supported upon cross-rods 2 2, which, with the bolts 3, form stay-bolts for the vessel. Angle-pieces 4 a may be bolted to the opposite sides of the vessel to serve as points of support.

The sugar-juice either after or before clarification is led by a pipe D, Fig. 1, into one end of the defecating vessel A and flows along the same and past the successive plates 0 in sequence. The scum portion is caused by the inclined plates 0 to rise to the top and flow over the plates, while the clear juice flows along below the plates.

A trough-shaped chamber E is fitted or formed at the end of the defecating vessel A to finally separate and receive the scum or froth from the liquor and run it away, said chamber being fitted with an adjustable plate E to regulate the height or discharge of scum, and a somewhat similar chamber F is fitted or formed at the end of the settling-chamber to receive and draw away the clear juice to the evaporators, these two chambers being formed by a partition g, extending from the top of the vessel downwardly and forwardly and terminating at a point near the bottom thereof. This chamber F is formed with an inclined end F for the sediment or mud to be drawn off at bottom through a valve F.

I claim as my invention 1. A defecator for sugar-juice and like liquors, consisting of a heating vessel havingan inlet for the juice at one end, scum and juice separating plates at spaced distances apart within the vessel, each terminating below the top and above the bottom thereof, whereby the scum is caused to flow above the plates and the juice below the same, and a partition near the opposite end of the vessel and terminating above the bottom and forming a chamber on one side thereof for receiving the scum flowing from the inlet end of the vessel above the plates, and a chamber on the other side thereof for receiving the clear juice fiowing below said plates, substantially as described.

2. A defecator for sugar-juice and like liquors comprising a main vessel having an inlet for the juice at one end, scum and juice separating plates within said vessel at spaced distances apart, a plurality of independent steam-jacketed chambers for heating the vessel, each provided with a separate steam-supply valve, and scum and juice separating chambers at the Opposite end of said vessel, substantially as'described.

3. A defecator for sugar-juice and like liquors, comprising a main vessel with inclined scum and juice separating plates at spaced distances apart, steam-jacketed chambers and scum and juice separating chambers at the end of the vessel, substantially as set forth. I

In testimony whereof I have signed my name to this specification inthe presence of two subscribing witnesses.

FREDERIO I. SOARD.
